Systems and methods for detecting physiological information of a user
First Claim
1. An apparatus for sensing and measuring at least one physiological parameter of a person, the apparatus comprising:
- a housing comprising a front face, a rear face, and an interior region located between the front face and the rear face, at least a portion of the rear face configured for contact with a targeted area;
a sensor for sensing at least one physiological parameter, the sensor comprising at least one light source for illuminating the targeted area, at least one optical detector for receiving reflected light from the targeted area, and at least one substrate to which the at least one light source and the at least one optical detector are mounted; and
at least one optical barrier between the at least one light source and the at least one optical detector, the at least one optical barrier comprising a laterally-extending portion and a vertically-extending portion extending from the laterally-extending portion toward the targeted area, both portions positioned on a same side of the substrate as the at least one light source and the at least one optical detector for preventing direct light transmission from the at least one light source to the at least one optical detector.

Abstract
Described herein are systems and methods for improving the reliability and accuracy of wearable physiological monitoring devices. A wearable monitoring device may comprise an inner surface configured for at least partial contact with a targeted tissue region of a person. The inner surface may comprise one or more outwardly projecting raised regions. The monitoring device may further comprise a physiological sensor, one or more components of which may be located at or near a raised region of the inner surface. In this manner, sufficient contact between the targeted tissue region and the inner surface, as well as proper placement of the one or more components of the sensor relative to the targeted tissue region, may be achieved. The accuracy and reliability of the monitoring device may also be less susceptible to the effects of ambient light and/or the movements of the user.

9. A device for monitoring at least one physiological parameter of a person, the device comprising:
-
an elongate body comprising a front face, a rear face, and an interior region defined between the front and rear faces, at least a portion of the rear face configured for contacting a targeted tissue region; a sensor for detecting at least one physiological parameter of the person comprising at least one light source, at least one optical detector, and at least one substrate to which the at least one light source and the at least one optical detector are mounted; and at least one optical barrier between the at least one light source and the at least one optical detector, the at least one optical barrier comprising a laterally-extending portion and a vertically-extending portion extending from the laterally-extending portion outward to the targeted tissue region, both portions positioned on a same side of the substrate as the at least one light source and the at least one optical detector for preventing light transmission from the at least one light source directly to the at least one optical detector. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A wearable apparatus for monitoring at least one physiological parameter, the apparatus comprising:
-
a body comprising a rear face, at least a portion of the rear face configured for contact with a targeted area; an optical sensor comprising at least one light source, at least one optical detector, at least one substrate to which the at least one light source and the at least one optical detector are mounted, and at least one substantially transparent member; and at least one optical barrier comprising a laterally-extending portion and a vertically-extending portion extending between the laterally-extending portion and the targeted area, both portions positioned on a same side of the substrate as the at least one light source and the at least one optical detector for preventing light transmission from the at least one light source directly to the at least one optical detector. - View Dependent Claims (17, 18, 19)
